Abstract

IN a recent communication we reported our first results on the application of ESCA (electron spectroscopy for chemical analysis) to the element carbon in organic molecules1. 1s electrons of carbon expelled by aluminium Kα radiation were found to form two well separated electron lines in benzenecarboxylic acid; one line corresponded to the benzene carbon and the other to the carboxyl carbon. The energy difference was 4 eV. Since then we have found many similar chemical shift effects for carbon in various organic compounds. Here we report some results involving the element nitrogen.
